“More products, better results.” 31 supplements.
One sachet or scoop.
30 seconds a day.

Most routines fail by March, not because the formulas are wrong, but because nobody keeps opening 7 tubs. OneFit replaces the cupboard with one sachet you’ll actually take every day.

Nobody plans to end up here

Nobody plans to end up with four containers on the shelf. It happens one product at a time, each one bought for a good reason. Until there are more decisions on the counter than any morning has time for. OneFit is the way back to one.

Four tubs or one: four bulky, unlabelled black supplement tubs crowded on a bench behind a single OneFit Advanced Multi-Supplement sachet
02

A supplement you skip does nothing

A supplement sitting unused in a cupboard does nothing, no matter what the label promises. The first ones to go are always the fiddly ones. And the fiddly ones are usually the ones with a real dose in them. OneFit’s easy enough that it doesn’t become one of them.

The same shelf at week 1 and at week 8: crowded with open, unlabelled supplement containers to begin with, and down to two untouched ones by the end

One serve is one decision. That is the entire mechanism.

03

Most of your stack is optional.
Protein isn’t.

Most of a stack is optional at the margins. Protein isn’t. It’s what actually builds and holds lean mass, and it’s the one item people skip first because it needs a shaker and thirty seconds. 25g in OneFit’s serve, alongside everything else, removes that excuse.

Your problem isn’t consistency.
It’s inventory.

Nobody quits their routine because it’s too hard. They quit because tub #2 of 4 ran out and reordering fell off the list. OneFit is the whole shelf in one scoop, so the only thing you have to remember is water.

Four a day or one: a scoop of powder, two capsules, a spoon of salt and a tablet scattered across one half of a bench, a single OneFit sachet and a glass of water on the other
05

Named on the label, not in the dose

This is the fair objection to every all-in-one, and it’s usually correct. An ingredient gets added at a dose too small to matter, just so it can be named on the front. Check the number per serve. On OneFit, that’s the only one that counts.

Dosed at the amount that’s actually studied

Every ingredient in OneFit is dosed at the amount it’s actually studied at. 25g protein, 5g creatine, 1,000mg L-Carnitine, a gram of electrolytes, 16 vitamins and minerals. One sachet, 100 calories, once a day.

Still taking it, nothing skipped

Week 4 on OneFit, still taking it, nothing skipped. Week 8, it starts showing, leaner and more defined. Week 12, the difference is obvious, and it’s still just one sachet every morning. Individual results vary and depend on training, diet and consistency.

The questions everybody asks.

Isn’t an all-in-one always a compromise?

Usually, yes, and it is a fair thing to assume. Most blends include an ingredient at an amount too small to do anything so the name can go on the front. The test is not whether a product calls itself complete, it is whether the per-serve figures match what the research on each ingredient actually used. Ours are printed on the sachet and in the table at the bottom of this page: 25g protein, 5g creatine, 1,000mg l-carnitine, 1g of elemental electrolytes. Check them against anything else you are considering.

What exactly does it replace?

For most people: a protein powder, a creatine tub, an electrolyte powder and a multivitamin, plus a probiotic if they were taking one. That is the basket priced out in the comparison further up this page. It does not replace whole food, and it does not replace anything you have been prescribed.

Can I still take other things alongside it?

Yes, and plenty of members do. Vitamin D and fish oil are the two that come up most, because neither is in the formula. The point of the page is not that you should take fewer things on principle. It is that the four or five things most people are already buying can be one thing, at the doses that made them worth buying.

Why does everything have to be in one serve?

Because the alternative is four decisions a day and the evidence of your own cupboard on how that goes. A supplement sitting unopened has an effect of exactly zero whatever is printed on it, and the ones that get abandoned first are the fiddly ones, which are usually the ones carrying a real dose. One serve is one decision.

Is it actually cheaper?

On the comparison above, yes, and the figures are itemised so you can check them rather than take the claim. Two caveats stated plainly: those are indicative retail prices for eight comparable products, and FON’s own published basket figure and the sum of the eight line items do not currently agree. The summary uses the lower of the two, which is the less flattering one.

How much is in OneFit®, and how do I take it?

31 ingredients per 35g serve, at 100 calories: one sachet or one scoop, shaken into 300ml of water or a beverage of your choice. One serve daily. That is the whole routine.

When should I take it?

After training, ideally. Exercise acutely increases metabolic responsiveness, so that’s the most useful window. On rest days take it at the same time each day. Daily consistency matters more than perfect timing, which is most of the argument this page is making.

Who is it for?

People already taking a protein, a creatine, an electrolyte product and a multivitamin separately who want that down to one daily serve instead of four. It isn’t a replacement for meals, and it isn’t built for someone who only wants a single ingredient in isolation.

What if I don’t like it?

You’re covered by a 90-day full refund guarantee, and you can cancel or pause a subscription at any time. If it’s the flavour rather than the formula, the flavour promise lets you swap within 24 hours.
